CAR-VESTIBULE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed July 31,1905. Serial No. 271,930.

To n/ZZ whom it may concern:

Be it known that we, JOHN P. SJOBERG and ERNST L. FoRseREN, citizens of the United States, residing at New York, in the county of New York andState of New York, have invented certain new and useful Improvements in Car-Vestibules, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a new and improved car-vestibule for use in connection with trolley cars and the like whereby a motorman or conductor may open one of the windows of said vestibule, if he so desires, a further object being to provide a vestibule of this class which employs straight or flat glass throughout, thereby overcoming the necessity for the use of curved sheets of glass, as heretofore employed, and a still further object being to provide means whereby a sash in said vestibule, although fiat instead of curved, may be made to slide backwardly and forwardly in a substantially curved-like way without injury to said sash or the glass therein.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which.

Figure l is an inside view of a vestibule for trolley-cars constructed according to our invention; Fig. 2, a horizontal section thereof on the line 2 2 of Fig. 1; Fig. 3, a detail of an antirattling device Wlllul] we employ; Fig.

4, a detail view, partially in section, of aswivelhanger which we employ; and Fig. 5, a view of a modification thereof.

In the drawings forming part of this specification wehave shown a car-vestibule a, composed of a top member a a bottom member and a plurality of upright posts Z2 b 6*, Z)", and 5, thereby forming five -light-spaces In Fig. 2 of the drawings we have shown the space between the posts 6 and 6 Z and Z Z2 and b and Z and Z) each provided with a sheet of glass 0,

which is immovable therein; but, as will be seen, the space between the posts 6 and Z2 is not so provided; but movably mounted directly to the rear thereof is a sash cZ, provided with a sheet of glass (Z and with hangers (Z engaging and movable on an overhead track 6Z5, secured to the uprights Z 6 and Z7 and conforming to the configuration of the vestibule, as shown in Fig. 2.

Secured to the bottom member a between the uprights 72 6 and If is a guide member 0. which extends to a position adjacent to the bottom of the sash (Z, but permitting the sash (Z to move thereover, and the top of the sash (Z is likewise permitted to move beneath the track (Z as clearly shown in Fig. 1.

Secured to the bottom of the sash (Z are two guides or antirattling devicesfieach of which consists of a plate member f and a roller f rotatabl y mounted at the bottom thereof, said roller being adapted to operate against the inner side of the guide strip or rail 0', and it will be seen with reference to Fig. 1 that when the antirattling devicesf move in the groove formed by the guide strip or rail 6 past one of the angles of said strip, the sash (Z may pass over said guide-rail e at the angular portion thereof, and said sash is not impeded in its movement, as will be readily seen.

In Fig. 4 we have shown our preferred form of swivel-hanger, which consists of a plate 9, in which is mounted a rotatable vertical rod g in the upper end of which is secured a shaft 9 upon which rotates the pulley or roller g", which is adapted to engage the overhead track 9 and when the sash (Z is operated the rollers g, because of the swivel arrangement of the rods 9 adapt themselves to the direction of the track (Z and when an angular portion of said track is being passed by said hangers the sash (Z may pass thereunder and not be impeded thereby in its movement.

In Fig. 5 of the drawings we have shown a slightmodification of the swivel-hanger shown in Fig. I, in which the plate 9 is continued upwardly to form a rod upon which is rotatably mounted an arm g which carries the rotatable pulley or roller and it will be seen that in either of the forms. of hangers shown not only is the pulley or roller rotatable upon its axis, but the axis thereof is rotatable on the supporting-plate.

It will therefore be seen that our invention permits of the use of flat sashes and flat glass sheets therein and permits of the movement of one of said sashes in said vestibule, and while we have shown two forms of the swivelhangers and one form of the antirattling device it will be obvious that many other forms thereof may be devised and employed, it being necessary, however, to provide a swivelhanger for the movable sash, and this constitutes the gist of our invention, and when the glass is ina closed position We provide a catch it of any suitable form or construction, which may also serve as a handle in the manipulation of said sash.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A car-vestibule, comprising an angular frame composed of a plurality of plain surfaces, and a sash slidably movable from one of said plain surfaces to another thereof, sub-' stantially as shown and described.

of said plain surfaces to another thereof, said sash being supported on an overhead track arranged in said frame, and being held thereon by means of swivel-hangers, substantially as shown and described.

4. In a car-vestibule composed of a plurality of plain surfaces or faces, an angular track, a sash, and swivel-hangers secured to said sash and onto said track, substantially as shown and described.

5. In a car-vestibule composed of a plurality of plain surfaces or faces, an angular track, a sash, and swivel-hangers secu red to said sash and onto said track and antirattling devices arranged on the bottom of said sash adapted to guide the same in the movement thereof, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses,this 28th day of July, 1905.
